A personal name, full name or prosoponym (from Ancient Greek prósōpon – person, and onoma –name) is the set of names by which an individual person or animal is known. When taken together as a phrase, they all relate to that one individual. In many cultures, the term is synonymous with the birth name or legal name of the individual. In linguistic classification, personal names are studied within a specific onomastic discipline, called anthroponymy.
In Western culture, nearly all individuals possess at least one given name (also known as a first name, forename, or Christian name), together with a surname (also known as a last name or family name). In the name "James Smith", for example, James is the first name and Smith is the surname. Surnames in the West generally indicate that the individual belongs to a family, a tribe, or a clan, although the exact relationships vary: they may be given at birth, taken upon adoption, changed upon marriage, and so on. Where there are two or more given names, typically only one (in English-speaking cultures usually the first) is used in normal speech.
